Dermoscopy, commonly used to analyze skin tumors, has more recently been used to evaluate inflammatory dermatoses. We performed a systematic review of the literature to assess the role of dermoscopy in evaluating psoriasis, and briefly reviewed the findings with an emphasis on the specificity or sensitivity of the dermoscopic findings of psoriasis. We also describe the case of a 63-year-old man with a history of psoriasis and basal cell carcinoma (BCC) who presented with a new scaly pink patch on the back. This case highlights the importance of dermoscopy in differentiating patches and plaques of psoriasis from BCC...

OBJECTIVES: The incidence and mortality of melanoma are increased in organ transplant recipients. Multiple acquired common and dysplastic nevi are risk factors for melanoma. A new or changing nevus may suggest melanoma. Strategies used by transplant dermatologists to monitor nevi are unknown. Herein, we aimed to assess the methods used by transplant dermatologists for monitoring multiple acquired common nevi, dysplastic nevi, and new or changing nevi. MATERIALS AND METHODS: A questionnaire was e-mailed to 63 members of the Skin Care in Organ Transplant Patients, Europe...

BACKGROUND/PURPOSE: Acral melanoma is the most common type of melanoma in Asians, and usually results in a poor prognosis due to late diagnosis. We applied a convolutional neural network to dermoscopy images of acral melanoma and benign nevi on the hands and feet and evaluated its usefulness for the early diagnosis of these conditions. METHODS: A total of 724 dermoscopy images comprising acral melanoma (350 images from 81 patients) and benign nevi (374 images from 194 patients), and confirmed by histopathological examination, were analyzed in this study...

Acral lentiginous melanoma (ALM) is the most common type of malignant melanoma (MM) in Asians, Afro-Americans and Middle-Easterns. It represents 1.5-10% of all MM cases, being the most common histological type of MM arising on palms, soles and nail apparatus, which is more generically defined as acral MM. To date no risk factors have been officially established, however a history of trauma may be involved in the pathogenesis of acral MM. This shows heterogeneous clinical features and frequently presents with advanced stage and aggressive behaviour, often as a result of misdiagnosis or delayed identification...

BACKGROUND: Malignant melanomas mimicking seborrheic keratosis (SK-like MMs) carry the risk of delayed diagnosis and inadequate treatment. The value of dermoscopy to improve the correct detection of these mimickers has not been previously studied. OBJECTIVE: To evaluate the diagnostic accuracy of clinically SK-like MMs with and without dermoscopy. METHODS: Clinical and dermoscopic images of histopathologically proven SK-like MMs (n = 134) intermingled with other melanomas and benign tumors were randomly presented to clinicians with different levels of experience, blinded to the diagnosis and goal of the study...

Pediatric melanoma is a rare disease that affects approximately 6 out of every one million children and accounts for 1-4 percent of all melanomas. This article reviews the epidemiology, etiology, diagnosis, treatment and prognosis of pediatric melanoma - with particular attention to recent updates in the literature. While awareness of melanoma increases among the general population, recent data suggest stable and even declining incidence rates among certain pediatric populations. Studies have examined clinical features and presentations of melanoma among the pediatric population and the conventional ABCDE criteria used to diagnosis adult melanoma may not be entirely appropriate for pediatric melanoma; as such, additional pediatric-ABCD and CUP criteria have been proposed...

Small pigmented lesions in children can represent a significant diagnostic challenge. If the diagnostic features and therapeutic approach are relatively well established in large and giant nevi, there is still much controversy regarding small and intermediate-sized congenital pigmented lesions that can lead to significant diagnostic challenges, both clinically and dermoscopically, and consequently to difficulty in defining the optimal approach in such cases. Although dermoscopy can be useful in the diagnosis of pigmented lesions, the diversity of clinical and dermoscopic features of pigmented nevi in children usually hinder the differentiation between them and melanoma...

BACKGROUND: Histiocytic sarcoma (HS) is an extremely rare, non-Langerhans cell tumor. HS affects especially adults, its etiology is unknown yet. Skin could be interested by papules or nodules, single or multiple. CASE REPORT: A Caucasian man in his late 40s came to our clinic for a naevi evaluation. During the visit, a rose papulonodular lesion was observed in the lumbar region. This lesion was completely asymptomatic, and it had been there for an indefinite period...

BACKGROUND: Subungual exostosis is a relatively uncommon, benign osteocartilaginous tumor of the distal phalanx of the toes or fingers in young adults, considered as a rare variant of osteochondroma. Differential diagnoses include subungual verruca (viral wart), pyogenic granuloma, osteochondroma, amelanotic subungual melanoma and glomus tumour. Misdiagnosis and total onychodystrophy frequently occur as a result of late treatment or inadequate treatment strategy. Dermoscopy could be a useful technique, involved in the diagnostic process, although X-ray examination and histopathology are mandatory for the diagnosis...

A 75-year-old man presented to the dermatology clinic with an asymptomatic lesion on his right plantar surface. The lesion had progressively grown for two months. Physical examination revealed an erythematous and slightly scaly nodule measuring 10x10 mm. Dermoscopy examination showed central diffuse erythema with small red globules. A punch-biopsy revealed a proliferation of irregularly branched small vessels with collapsed lumen, extending in an infiltrative pattern in the superficial and deep dermis. Although this is a rare location, a diagnosis of microvenular hemangioma was made...

Monilethrix is a rare genodermatosis characterized by a hair shaft dysplasia responsible for hypotrichosis. We report the case of a child with monilethrix with no associated cases in the family. Trichoscopy facilitated the diagnosis. A 2-year-old boy presented with diffuse alopecia and persistent fragile hair for several months. Clinical examination revealed alopecia with hairs broken several millimeters from the scalp. Trichoscopy revealed zones of dystrophic constriction of the hair shaft, separated at regular intervals by elliptical nodes of normal thickness, giving a "necklace" appearance...

BACKGROUND: Management of alopecia areata (AA) and androgenetic alopecia (AGA) is often challenging. The use of carboxytherapy may be a novel therapeutic option for such cases. OBJECTIVE: To evaluate the clinical efficacy and safety of carboxytherapy in alopecia areata and androgenetic alopecia. PATIENTS AND METHODS: This study was conducted on 80 patients with alopecia divided into two groups; Group I included 40 AA patients (Group IA received carboxytherapy and Group IB control received placebo), and Group II included 40 AGA patients (Group IIA received carboxytherapy and Group IIB control received placebo), and followed up monthly for 3 months...

The trichoscopic features of frontal fibrosing alopecia (FFA) have been described in the frontotemporal area, yet there is no data detailing the trichoscopic features of the sideburns, which can be the initial or exclusive area of involvement. In this retrospective cohort study, 236 trichoscopic images of the frontotemporal and sideburn area obtained via dry trichoscopy from patients with biopsy-proven FFA were examined by two independent researchers to determine the trichoscopic features of FFA in the sideburns...

Linear scleroderma en coup de sabre (LSCS) is the most common form of morphea on the scalp and its trichoscopic features have not been described yet. We report 2 adult women with LSCS with distinct dermoscopic findings. They both had an atrophic well-defined linear patch of alopecia on the frontotemporal scalp. Dermoscopy showed loss of follicular openings on a whitish skin surface; scattered black dots, broken hairs, and pili torti; and short thick linear and branching tortuous vessels on the periphery of the lesion...

Beard trichotillomania (TTM) is a rather uncommon entity. Hair is not easily plucked from the beard area, as patients need forceps or tweezers to perform their task. The diagnosis of beard TTM can be quite tricky as the location is not the most frequent one. Dermoscopy might in these cases be helpful to achieve the correct diagnosis. In this article, we describe for the first time the "pluck out sign" for beard TTM.

OBJECTIVE: Exclusion of psoriatic skin/nail lesions is important in differentiating early seronegative rheumatoid arthritis (ERA) from early polyarticular psoriatic arthritis (EPsA) and such manifestations may go unnoticed in atypical or minimally expressed cases. The aim of this study is to assess the usefulness of integrated rheumatological-dermatological evaluation in highlighting dermatological lesions missed on rheumatological examination and to investigate the role of ultrasonography (US) and dermoscopy in improving the recognition of subclinical psoriatic findings...
